CVSS: 8.8EPSS: 0%CPEs: 1EXPL: 0CVE-2021-29468 – Arbitrary code execution when checking out an attacker-controlled Git branch
https://notcve.org/view.php?id=CVE-2021-29468
Cygwin Git is a patch set for the git command line tool for the cygwin environment. A specially crafted repository that contains symbolic links as well as files with backslash characters in the file name may cause just-checked out code to be executed while checking out a repository using Git on Cygwin. The problem will be patched in the Cygwin Git v2.31.1-2 release. At time of writing, the vulnerability is present in the upstream Git source code; any Cygwin user who compiles Git for themselves from upstream sources should manually apply a patch to mitigate the vulnerability. As mitigation users should not clone or pull from repositories from untrusted sources. • https://cygwin.com/pipermail/cygwin-announce/2021-April/010018.html https://github.com/me-and/Cygwin-Git/blob/main/check-backslash-safety.patch https://github.com/me-and/Cygwin-Git/security/advisories/GHSA-rmp3-wq55-f557 https://lore.kernel.org/git/CA+kUOa=juEdBMVr_gyTKjz7PkPt2DZHkXQyzcQmAWCsEHC_ssw%40mail.gmail.com/T/#u • CWE-20: Improper Input Validation •
CVSS: 8.0EPSS: 85%CPEs: 21EXPL: 12CVE-2021-21300 – malicious repositories can execute remote code while cloning
https://notcve.org/view.php?id=CVE-2021-21300
Git is an open-source distributed revision control system. In affected versions of Git a specially crafted repository that contains symbolic links as well as files using a clean/smudge filter such as Git LFS, may cause just-checked out script to be executed while cloning onto a case-insensitive file system such as NTFS, HFS+ or APFS (i.e. the default file systems on Windows and macOS). Note that clean/smudge filters have to be configured for that. Git for Windows configures Git LFS by default, and is therefore vulnerable. The problem has been patched in the versions published on Tuesday, March 9th, 2021. • https://github.com/AlkenePan/CVE-2021-21300 https://github.com/Maskhe/CVE-2021-21300 https://github.com/1uanWu/CVE-2021-21300 https://github.com/Roboterh/CVE-2021-21300 https://github.com/Saboor-Hakimi-23/CVE-2021-21300 https://github.com/Kirill89/CVE-2021-21300 https://github.com/erranfenech/CVE-2021-21300 https://github.com/fengzhouc/CVE-2021-21300 https://github.com/danshuizhangyu/CVE-2021-21300 https://github.com/Faisal78123/CVE-2021-21300 http://packetstormsecurity. • CWE-59: Improper Link Resolution Before File Access ('Link Following') •
CVSS: 7.5EPSS: 0%CPEs: 16EXPL: 0CVE-2020-11008 – Malicious URLs can still cause Git to send a stored credential to the wrong server
https://notcve.org/view.php?id=CVE-2020-11008
Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials to a host controlled by an attacker. This bug is similar to CVE-2020-5260(GHSA-qm7j-c969-7j4q). The fix for that bug still left the door open for an exploit where _some_ credential is leaked (but the attacker cannot control which one). Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that are considered illegal as of the recently published Git versions can cause Git to send a "blank" pattern to helpers, missing hostname and protocol fields. • http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00003.html http://seclists.org/fulldisclosure/2020/May/41 https://github.com/git/git/commit/c44088ecc4b0722636e0a305f9608d3047197282 https://github.com/git/git/security/advisories/GHSA-hjc9-x69f-jqj7 https://github.com/git/git/security/advisories/GHSA-qm7j-c969-7j4q https://lists.debian.org/debian-lts-announce/2020/04/msg00015.html https://lists.fedoraproject.org/archives/list/package-announce%40lists.fedoraproject.org/message/74Q7WVJ6FKLIN62VS2JD2XCNW • CWE-20: Improper Input Validation CWE-522: Insufficiently Protected Credentials •
CVSS: 9.3EPSS: 0%CPEs: 20EXPL: 2CVE-2020-5260 – malicious URLs may cause Git to present stored credentials to the wrong server
https://notcve.org/view.php?id=CVE-2020-5260
Affected versions of Git have a vulnerability whereby Git can be tricked into sending private credentials to a host controlled by an attacker. Git uses external "credential helper" programs to store and retrieve passwords or other credentials from secure storage provided by the operating system. Specially-crafted URLs that contain an encoded newline can inject unintended values into the credential helper protocol stream, causing the credential helper to retrieve the password for one server (e.g., good.example.com) for an HTTP request being made to another server (e.g., evil.example.com), resulting in credentials for the former being sent to the latter. There are no restrictions on the relationship between the two, meaning that an attacker can craft a URL that will present stored credentials for any host to a host of their choosing. The vulnerability can be triggered by feeding a malicious URL to git clone. • https://github.com/sv3nbeast/CVE-2020-5260 https://github.com/Asgavar/CVE-2020-5260 http://lists.opensuse.org/opensuse-security-announce/2020-04/msg00027.html http://lists.opensuse.org/opensuse-security-announce/2020-05/msg00003.html http://packetstormsecurity.com/files/157250/Git-Credential-Helper-Protocol-Newline-Injection.html http://www.openwall.com/lists/oss-security/2020/04/15/5 http://www.openwall.com/lists/oss-security/2020/04/15/6 http://www.openwall.com/lists/oss-security&#x • CWE-20: Improper Input Validation CWE-522: Insufficiently Protected Credentials •
